WILLIAM A. NEELY, OF LYNN, MASSACHUSETTS, ASSIGrNORv TO THE WHEELER &7 WILSON MANUFACTURING COMPANY, OF BRIDGE PORT, CONNECTICUT.

'PRESS ER-FOOT FOR SPECIFICATION forming part of Letters Patent No. 400,355, dated March 26, 1889.

' I Application filed September 18, 1888- Serial No. 285,692. (No models) To all whom it may concern Be it known that 1, WILLIAM A. NEELY, of Lynn, county of Essex, State of Massachusetts, have invented an Improvement in Presser-Feet for Sewing-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts. a This invention relates to improvements .in sewing-machines, and has for its object to provide a two needle machine with independent presser-feet, adapted to not only hold the work adjacent to the needles, but also to serve as a bridge between the needles, preventing them from fouling when in operation.

In accordance with this invention, the usual roller presser-foot is employed, and an inclependent foot is connected with the presserbar, preferably so as to yield, said independent foot occupying a position between the two needles of the needle'bar.

The under face of the independent yielding presser-foot is shaped to correspond substantially with the contour of the roller presser-foot to act or bear upon the work.

Figure 1 shows in end View the roller presser-foot, a portion of the needle-bar, the needles, and the independent presser-foot embodying this invention; Fig. 2, a side view of the parts shown in Fig. 1; and Fig.3, a detail of the independent presser-foot, to be referred to. Fig. 4 is an enlarged detail section on line a: 00 of Fig. 3.

The roller presser-foot a, connected to the bracket or arm I), attached to or forming part of the usual presser-bar, c, the needle-bar cl, its needles 2 3, and the throat-plate e are all as usual, so need notbe further described.

An independent presser-foot, f, is loosely connected with the presser-bar c by a pin, f,

passing through suitable ears, f secured to i the bracket or arm which carries the roller normally press the foot down upon the work. 7

The under face or contour of the presser= foot f is curved substantially like the cor responding contour of the roller presser-foot a. The presser-foot f occupies a position between the two needles 2 3, to thereby serve as a bridge or obstruction between them to prevent fouling when in operation.

The presser-foot f is made slightly Ashaped in cross-section, so as to present as wide a contact or bearing surface as possible and yet permit the free and unobstructed passage of the needles. In other words, said foot is a thin but rigid blade-like device with inclined sides, and is arranged edgewise Vertically between the two closelyadjacent needles, with its thinnest or sharpest edge upward to guide or deflect the needles to proper positions as they descend should they be slightly sprung or bent, and thus keep them from fouling, said rigid foot, owing to the spring f and the pivot pin or screw f, having a yielding connection with the shaft or arm I). In operation it will be seen that each presser-foot, as a f, occupies a position atthe same or corresponding side of its needle, and the presser-footf, being made yielding, as provided for by the spring, acts independently of the presser-foot athat is to say, it may rise and fall to compensate for irregularities in or on the surface of the work irrespective of the movement of the presser-foot a.

It will also be seen that the independent presser-foot f serves to act or bear upon the work to hold it firmly in substantially the same manner as the presser-foot a.

It is obvious that the independent foot f might be attached directly to the presser-bar, in lieu of being attached to the bracket or arm carrying the roller presser-foot, as herein shown.

I claim- 1. In a sewing-machine having two closelyadjacent needles, the combination, with a roller presser-foot, of an independent presserfoot consisting of a thin blade-like device arranged edgewise vertically between said needles, substantially as set forth.

2. In a sewing-machine having two closelyadjacent needles, the combination, with a roller presser-foot, of an independent presserfoot consisting of a thin blade-like device arranged edgewise vertically between said needles and having a yielding or spring connection with the arm or shank to which it is attached, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

WILLIAM A. NEELY.
